Buried Treasure: 'Back to the Future' trilogy is one nostalgic time trip

In the neverending quest for cinematic gems hidden in the weekly TV listings, here's what I'll be watching (or recording) this weekend:

Christopher Lloyd and Michael J. Fox in 'Back to the Future.'

What: The "Back to the Future" trilogy, directed by Robert Zemeckis and starring Michael J. Fox as a time-traveling teen out to undo the changes he unintentionally makes to his future life.

When: Saturday (Nov. 6), 2:30 p.m.

Where: ABC Family

Why: There are those who can afford the 25th anniversary Blu-ray edition of these 1980s classics, released in one giant box set a couple of weeks ago. For the rest of us, this wonderfully timed marathon will do nicely in taking us back to the past. It should deliver all the nostalgia you need for one night, and without the 1.21 gigawatts Doc Brown needed to fling Marty McFly through the space-time continuum. Watch it -- it's your density.
